<u>Step 1: Assign variable for the unknown that you need to find. </u>
Let ' t ' be the number of hours it took for the pedestrians to meet.
<u>Step 2: List the give details</u>
Speed of first pedestrian = 4 km/hr.
Speed of second pedestrian = 6 km/hr.
Distance between two pedestrians = 27 km.
<u>Step 3: Set up an equation</u>
The relationship between speed, distance and time is given below:
The first one walked 4 km per hour, distance traveled by first pedestrian is given below:
Two pedestrians simultaneously left two villages 27 km apart and walked toward each other.
Conclusion:
The pedestrian meet after 2.7 hours.
So Jj earns a flat rate of 180 per week and an extra 15 per tablet he has sold
so what we need to do is subtract his flat rate(180) from his total(315)
315
-180
____
135 So now we know how much money Jj has earned from selling tablets. But we still need to create an equation and find out how many he has sold.
So we know he get $15 per tablet so 135÷15=9
now we know he has sold 9 tablets
Bu what is our Equation?
well, what were the steps?
TP = total pay
FR= Flat rate
C= Computer profit
PPC= price per computer
#C = number of computers
#C = TP-FR=C C÷PPC=#C
can we simplify this further?
#C = C÷PPC
lets do this:
#C= x
C= y
PPC= z
So: (X = Y÷Z)
Answer:
$2.48
Step-by-step explanation:
He paid $20 and got $12.56 back so you subtract
20-12.56=7.44
So his total was 7.44 and he bought 3 bags so divide to find the individual price
7.44/3=2.48
So $2.48
Answer:
x = -5.975
Step-by-step explanation:
distribute first by multiplying 2/5 by 'x' and then by 9/10 to get:
2/5x - 18/50 = -2 3/4
next, change -2 3/4 into an improper fraction to get:
2/5x - 18/50 = -11/4
now add 18/50 to -18/50 and to -11/4 using a common denominator of 100
2/5x = -275/100 + 36/100
2/5x = -239/100
multiply each side by 5/2 to isolate 'x':
x = -239/100 · 5/2
x = -1195/200
now simplify:
x = -5.975
Answer:
6 men 6 women or 2 men 10 women
